Despite winning three of the past four grand slams, Williams remains at world number two in the WTA rankings behind Dinara Safina, but she brushed off the controversy.

"Everybody thinks that I am number one, so that's fine with me," she said.

Despite being the higher seeded player, Serena went into the final as the underdog after her sister's demolition of Safina in the semifinals.

By contrast, the eventual champion survived a match point before beating Elena Dementieva in her last four clash and felt she had nothing to lose against her sibling who was chasing a sixth Wimbledon title.

"In the semis I didn't play play my best tennis and I know going into the finals I could play that way.

"I didn't want to lose in 10 minutes so Venus forced me to play better."

The sisters also paired up to win a fourth Wimbledon women's doubles title as they beat Australia's Samantha Stosur and Rennae Stubbs, 7-6 6-4.
